* GstMemory is a lightweight refcounted object that wraps a region of memory.
* They are typically used to manage the data of a #GstBuffer.
*
+ * A GstMemory object has an allocated region of memory of maxsize. The maximum
+ * size does not change during the lifetime of the memory object. The memory
+ * also has an offset and size property that specifies the valid range of memory
+ * in the allocated region.
+ *
* Memory is usually created by allocators with a gst_allocator_alloc()
* method call. When NULL is used as the allocator, the default allocator will
* be used.
* gst_memory_get_sizes() and gst_memory_resize() respectively.
*
* Getting access to the data of the memory is performed with gst_memory_map().
+ * The call will return a pointer to offset bytes into the region of memory.
* After the memory access is completed, gst_memory_unmap() should be called.
*
* Memory can be copied with gst_memory_copy(), which will returnn a writable
